Why at first the Romans banned Christianity in Rome?

A:Far from being banned from Rome in its earliest days, Christianity seems to have found a place there almost from the beginning. Paul wrote to the Roman Christians, and appears to have intended to visit them. A few years later, the Great Fire of Rome was thought to have broken out in the area of Rome where Christians were known to congregate, leading Emperor Nero to blame them, probably unfairly, for starting the fire. Christianity seems to have been well established in Rome by 95 CE, when Clement of Rome wrote his epistle now known as 1 Clement. By the third century, the Christian Church owned properties and imposing churches in Rome.
